The news is that a controversial little coelurosaur from the Isle of Wight’s Wessex Formation, Calamosaurus foxi (known only from two cervical vertebrae, one of them incomplete), is so similar to the cervical vertebrae of Dilong that I am confident that it too should be identified as a basal tyrannosauroid.

If so-called compsognathids – all of them relatively small, ecologically and morphologically generalized, long-limbed, long-tailed theropods that hunt small vertebrate prey – are not a clade but are actually scattered about the base of the coelurosaur family tree, this likely indicates that this ecotype was the ancestral one for coelurosaurs.
